Salon, an online publication, had a story last year on "Five Crazy Schemes for More Water" (http://www.salon.com/2012/09/20/five_crazy_schemes_for_more_water/), which were:
Download this spreadsheet: http://www.usna.edu/Users/oceano/pguth/downloads/CLIMATE_TEMPLATE.xls
Download this KMZ file: watering_las_vegas.kmz and open it in Google Earth. It has a series of points across California and Nevada to Las Vegas. There are also two points near Great Basin National Park, which is the proposed source for more water for Las Vegas. For each point there is a link to the web site of the FAO (Food and Agricultural Organization of the UN), which provides a climate model for the point. This model is generalized, and in particular does not accurately capture the peaks and valleys of the Great Basin, but provides a rough picture that is qualitatively acceptable.
The FAO says about this data: "The data available in the data-set refer to mean circumstances that are obtained by interpolating data from different climate stations. The data give an indication of climatic conditions but can never replace data obtained through stations. For more accurate assessments, it is therefore advisable to use as much as possible locally measured climate data."
Fill out the following table for the stations (this will probably be most easy in Excel, into which you can paste the table).
|Location||Elevation||July Mean T||Ann Precip||Annual Eto||dz||dt||lapse||Water budget|
You can get graphs of the climate by cutting the data from the FAO website, and pasting it into the spreadsheet you downloaded. There are directions in the spreadsheet; it is a two step process. If you use the spreadsheet, all the graphs will look the same, and you can easily compare them.
Answer the following questions, in a Word Document or PPT presentation turned in by the end of class. You will work in four groups of 3-4 each, and divide up the work within the group. The section leader is responsible to see there in only one group has 4 students.
